When the United States declared war on Germany in April 1917, it was woefully unprepared to wage a modern war. Whereas their European counterparts already had three years of experience in using code and cipher systems in the war, American cryptologists had to help in the building of a military intelligence unit from scratch. This book relates the personal experiences of one such character, providing a uniquely American perspective on the Great War. It is a story of spies, coded letters, plots to blow up ships and munitions plants, secret inks, arms smuggling, treason, and desperate battlefield messages. Yet it all begins with a college English professor and Chaucer scholar named John Mathews Manly. In 1927, John Manly wrote a series of articles on his service in the Code and Cipher Section (MI-8) of the U.S. Army’s Military Intelligence Division (MID) during World War I. Published here for the first time, enhanced with references and annotations for additional context, these articles form the basis of an exciting exploration of American military intelligence and counter-espionage in 1917-1918. Illustrating the thoughts of prisoners of war, draftees, German spies, and ordinary Americans with secrets to hide, the messages deciphered by Manly provide a fascinating insight into the state of mind of a nation at war.

Watch Craig Bauer discuss the Zodiac Killer's cipher on HISTORY's miniseries The Hunt for the Zodiac Killer In 1953, a man was found dead from cyanide poisoning near the Philadelphia airport with a picture of a Nazi aircraft in his wallet. Taped to his abdomen was an enciphered message. In 1912, a book dealer named Wilfrid Voynich came into possession of an illuminated cipher manuscript once belonging to Emperor Rudolf II, who was obsessed with alchemy and the occult. Wartime codebreakers tried--and failed--to unlock the book's secrets, and it remains an enigma to this day. In this lively and entertaining book, Craig Bauer examines these and other vexing ciphers yet to be cracked. Some may reveal the identity of a spy or serial killer, provide the location of buried treasure, or expose a secret society--while others may be elaborate hoaxes. Unsolved! begins by explaining the basics of cryptology, and then explores the history behind an array of unsolved ciphers. It looks at ancient ciphers, ciphers created by artists and composers, ciphers left by killers and victims, Cold War ciphers, and many others. Some are infamous, like the ciphers in the Zodiac letters, while others were created purely as intellectual challenges by figures such as Nobel Prize-winning physicist Richard P. Feynman. Bauer lays out the evidence surrounding each cipher, describes the efforts of geniuses and eccentrics--in some cases both--to decipher it, and invites readers to try their hand at puzzles that have stymied so many others. Unsolved! takes readers from the ancient world to the digital age, providing an amazing tour of many of history's greatest unsolved ciphers.

Decode the story of Elizebeth Friedman, the cryptologist who took down gangsters and Nazi spies In this picture book biography, young readers will learn all about Elizebeth Friedman (1892–1980), a brilliant American code breaker who smashed Nazi spy rings, took down gangsters, and created the CIA's first cryptology unit.

From thwarting notorious rumrunners with only paper and pencil to “counter-spying into the minds and activities of” Nazis, Elizebeth held a pivotal role in the early days of US cryptology. No code was too challenging for her to crack, and Elizebeth’s work undoubtedly saved thousands of lives. Extensive back matter includes explanations of codes and ciphers, further information on cryptology, a bibliography, a timeline of Elizebeth’s life, plus secret messages for young readers to decode.
